Application filed August 16. 1927. Serial No. 213,322.

The present improvement relates to metallic building elements, and more particularly to constructionadaptable for doors and framing units where glazing or other panel filling elements may be,employed.

It is among the objects of this invention to provide a construction which is simple and convenient for manufacture, strong and durable, consisting of few parts and pleasing in appearance, especially by the avoidance of exposed welded joints. Also the proposed construction is sanitary-and otherwise desirable by the elimination of exposed crevices between a multiplicity ofparts. ()ther objects and advantages will appear asthe description proceeds.

This invention consists of the features herein after described, and particularly pointed out in the claims; the following description and the annexed drawing setting forth but one illustrative embodiment of the various forms in which the principle may be applied.

"In said annexed drawing The sole figure shows part of the top of a door constructed in accordance with this invention. A

In the form illustrated the upper horizontal portion hereinafter called the top rail is indicated by the designating number 1, and this invention relates particularly to sheet metal framing elements of which top rail 1 is an example.

Said top rail 1. is of the type consisting of two independent halves having their position relative to one another located at assembly, so as to provide'a longitudinally extending slot therebetween.

Each half of the top rail consists of an outer shell 2 and an inner shell 3.

The inner shell 3 is so formed that it lays against the inner surface of outer shell 2 for the greater part of its area thereby reinforcing it for the application of door checks, closers, stops, or other attachments at any desired location throughout its length. The'inner shell 3 is so-formed at its margins as to strengthenit, and to bring them in contact with the margins of outer shell where they are Welded or otherwise fastened thereto. One design ofsaid forming is shown bringing one margin-in position to reinforce thepanel holding surface 4 of outer shell 2 and the other margin in position to reinforce the top surface rail 1 in all directions.

5 of the rail and the side 6 of the slot insertion and changing of panel.

The aforementioned welding or otherwise fastening ofboth edges of outer shell 2 and inner shell 3 results in strengthening the top Furthermore said welding is so located as to be concealed from view.

The outer shell 2 is so formed out of one continuous sheet of metal as to include integrally the face of the rail 1, the moulding or beading 7along the panel, the panel holding surface 4, the top surface 5, and side 6 of the slot for insertion and changing of panel.

Other modes of applying the principle of this invention may be employed instead of that explained, change being made as regards the features herein disclosed, provided the for means stated by any of the following claims or the equivalent of such stated means he employed,

lltherefore particularly point out and distinctly claim as my invention:

1. A rail for a metallic building unit, which comprises outer shell halves each presenting a hollow moulding at one edge, and an inner reinforcing shell lying against the outer shell for the greater part of its area and having a margin directed in contact with the inner face of the moulding of the outer shell.

2. A top rail for a metallic building unit,

which com rises outer shell halves each pre senting a attened surface and an inturned margin atone edge, and an inner reinforcing shell lying against each outer shell half for 5 the greater part of its area and having :1 margin bent successively to lie against the inturned margin and flattened surface of said outer shell.

3. A top rail for a metallic building unit, which comprises outer shell halves each presenting a hollow moulding at one edge and afiattened surface and an inturned margin at the other edge, and an inner reinforcing shell lying against each outer shell half for the greater part of its area and having one margin dir'ectedin contact with the inner face of the moulding of the outer shell and the other margin bent successively to lie against the inturned margin and the flattened surface of said outer shell.

Signed by me this 13th day of Au ust, 1927.
